Thread-topic: PCI device BCM5709 not works in DomU. ( On Dell PER610 box )

Hi:

I mapped my PCI NICs BCM5709 to DomU, and lspci can see them correctly.

But when I load the driver in DomU, I encounter this error in domU:

 

Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.8.5b (Feb 9, 2009)

PCI: Enabling device 0000:00:00.0 (0000 -> 0002)

PCI: Setting latency timer of device 0000:00:00.0 to 64

bnx2 0000:00:00.0: Cannot map register space, aborting.

bnx2: probe of 0000:00:00.0 failed with error -12

 

I use the same kernel between Dom0 and DomU, and the same driver works well in Dom0.

 

Tested in Xen-3.2.0,have the same problem.

But if I add the product id ‘14e4:1639’ into /etc/xen/xend-pci-permissive.sxp and rebuild initrd.img with “--preload pciback”, the BCM NIC can works well in DomU. 

( I find this method  from http://itknowledgeexchange.techtarget.com/linux-lotus-domino/centos-5-and-pciback-aka-hiding-pci-card-from-xen-dom0/  )

When I make the same configuration in Xen-3.3.1, it doesn’t work.

 

Does somebody meet the same problem?

All feedback is welcome.
